More than 5 million Americans are currently suffering from Alzheimer's disease, and scientists expect that number to triple in the next 30 years. That's why some of them here in California are pushing the line when it comes to testing new treatments for the disease.

The A4 Study is taking a new approach to Alzheimer's research by testing for an elevated level of a protein known as "amyloid" in the brain. Dr. Reisa Sperling is an internationally recognized Alzheimer's expert from Harvard University. She says that elevated amyloid may play an important role in the eventual development of memory loss and Alzheimer's. 

They've been testing whether a new drug can help slow the progress of memory loss, as well as looking at why certain populations are more prone to Alzheimer's. A couple of the research center are right in our backyard, at U.C. Davis and the Sutter Institute for Medical Research. They're looking for people between ages 65-80 with early signs or concerns about Alzheimer's to take part in their study.
